WIRELESS, INTERNET-BASED SYSTEM FOR MEASURING VITAL SIGNS FROM A PLURALITY OF PATIENTS IN A HOSPITAL OR MEDICAL CLINIC
First Claim
1. A system for measuring vital signs information from a plurality of patients comprising:
- a plurality of body-worn vital sign monitors, each worn by a patient and comprising;
1) a patch sensor system attached to a patient comprising at least two electrodes that each measures an electrical signal and an optical sensor that measures an optical signal from the patient;
2) a controller comprising a microprocessor that receives the electrical and optical signals from the patch sensor system and processes them to determine the patient'"'"'s vital sign information, including blood pressure; and
3) a short-range wireless transceiver that wirelessly transmits to an external transceiver the vital signs information and an identifying code indicating a specific body-worn vital sign monitor;
a portable, wireless monitor that receives vitals signs information and identifying code from each of the plurality of body-worn vital sign monitors, comprising;
1) a short-range wireless radio configured to receive the vital signs information and identifying code from each of the plurality of body-worn vital signs monitor;
2) a processor that processes the identifying code received from each unique body-worn vital signs monitor to identify it; and
3) a graphical user interface that displays;
i) information identifying at least one body-worn vital signs monitor that is in wireless communication with the external receiver; and
ii) vital signs information measured by the at least one body-worn vital signs monitor that is in wireless communication with the portable, wireless monitor.

Abstract
The invention provides system for measuring vital signs from multiple patients, typically in an in-hospital setting. The system features a body-worn vital sign monitor that includes: i) a sensor configured as a patch that measures electrical and optical signals from a patient; ii) a controller featuring a microprocessor that receives and processes the electrical and optical signals to determine the patient'"'"'s vital sign information, including blood pressure; and iii) a first short-range wireless component that wirelessly transmits a packet comprising the vital sign information to an external receiver. A portable, wireless computer (e.g., a PDA, cellular telephone, or a laptop computer) communicates with the body-worn module. The wireless computer includes: i) a second short-range wireless component that receives the vital sign information and displays it; and ii) a long-range wireless transmitter that transmits the vital sign information over a wireless network. The system also includes an Internet-based system that receives the vital sign information from the wireless network, and avails this to medical professionals through an in-hospital information system.
